I have used one of these as my primary dive light about ten years and it was great. However, I lost that one on the last dive trip to California's Channel Islands, I think the lanyard broke. The one I just purchased to rplace it was sitting on a counter when it got bumped and it fell 3 feet onto the carpet and now it won't work. I changed the bulb but it seems to be the switch which broke. I'll have to send it back to Princton to get it fixed. It doesn't seem to be as rugged as the first one I had but I'll stick with Princton anyhow.

turning on was tricky. The switch would not always turn on the light. At times the switch had to be in just the right location before the light would operate. It was not as easy as on off. And at times it would not turn on right away.

This is a solid light. The four batteries you need to power the light come with it...inside when you open it up. The light is ready to go in the box/tube. The case is well-designed and the "on" switch is easy to use. I bought it for the lumens and the price. I felt comfortable buying it because of the reviews. I feel comfortable using it because it performs like everyone says it does.
